POLYOL COMPOSITION FOR HARD POLYURETHANE FOAM, AND MANUFACTURING METHOD OF HARD POLYURETHANE FOAM USING THE SAME
PROBLEM TO BE SOLVED: To provide a polyol composition excellent in storage stability even when using only water as a foaming agent, a hard polyurethane foam excellent in dimensional stability of a foam even with low density and a manufacturing method therefor.SOLUTION: There is provided a polyol composition for hard polyurethane foam using organic polyisocyanate as a polyisocyanate component for obtaining a hard polyurethane foam, and using combination of polyether polyol consisting of polyalkylene oxide having equivalent molecular weights of 100 to 200 and 900 to 2200 as a polyol component and water of a specific amount as a foaming agent. There is provided a manufacturing method of a hard polyurethane foam using the composition.SELECTED DRAWING: None
